Always check this table before working on the fork.
Problem
Fork has too much sag
Forks bottoms too easily, but it
has the recommended sag
Fork bottoms too easily; needs
more than maximum preload
Fork does not get full travel
Fork extends too quickly; harsh
top-out after impacts
Front wheel wants to tuck
under while cornering
Fork "packs up" or stays
down in travel during multiple
impacts
Knocking sound during
rebound, but no harsh top-out
Oil "ring" on stanchions
Diagnosis
Spring rate too soft or fork oil
too fl uid
Not enough compression
damping
Spring rate too soft or fork oil
too fl uid
Spring rate too stiff or fork oil
level too high
